0x01 漏洞分析&复现
位于 /card/controller/CardController.php 控制器的toPost方法存在Curl_exec函数，且传参 str,url均可控，导致漏洞产生.
public function toPost($str,$url,$second=30){
//初始化curl
$ch = curl_init();
//设置超时
curl_setopt($ch, CURLOPT_TIMEOUT, $second);
//这里设置代理，如果有的话
//curl_setopt($ch,CURLOPT_PROXY, '8.8.8.8');
//curl_setopt($ch,CURLOPT_PROXYPORT, 8080);
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,FALSE);
curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,FALSE);
//设置header
curl_setopt($ch, CURLOPT_HEADER, FALSE);
//要求结果为字符串且输出到屏幕上
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
//post提交方式
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $str);
//运行curl
$data = curl_exec($ch);
//返回结果
if($data){
curl_close($ch);
return $data;
}else{
$error = curl_errno($ch);
echo "ERR";
curl_close($ch);
return false;
}
